interactive viewport & shifted cameras

hi everyone
i came across a strange behavior, when using interactive viewport (c4d r21, mac high sierra) and shifted camera.
no matter which settings (use render/selected view) are active, it isn’t showing the exact shifted camera view. the view is moved horizontally. “film offset x” is kinda messed up

see attached images

does anybody having the same issue?
thx for your inputs


I’m not able to reproduce that here, Can you share the scene with us?

i uploaded a simple test file using your link. it seems like it happens not only in my project, but in simple scenes, too.

Thanks! we’ll take a look and let you know what is found.
